Symantec Encryption Management Server Web Email Protection users running Internet Explorer 9 or 10 with the MS13-055: Cumulative Security Update for Internet Explorer: July 9, 2013 (KB2846071) update installed cannot add attachments to messages.

The problem occurs when a user tries to add an attachment to a Web Email Protection message doing the following:

Create a new message or reply to an existing one.

  1. Click on the paper clip icon or on Add attachment.
  2. Click on the Browse button to find a file and double click on it.
  3. Click on the Attach button.

This type of problem is acknowledged by Microsoft in the Known issues with this security update section of MS13-055:

After you install the security update for Internet Explorer 9 or for Internet Explorer 10 that is described in Microsoft security bulletin MS13-055, you may experience the following issues when you access some websites:

  • A browser window automatically closes and logs you out of a web session.
  • Drop down menus are not correctly populated.

 

No error is displayed for the user and the Symantec Encryption Management Server Web Email Protection log shows only the following when the user with email address [email protected] is replying to a message and trying to add an attachment:

Users with Internet Explorer 9 who have installed the update are also affected.

  1. Click Start > Control Panel.
  2. Select Programs.
  3. Under Program and Features, click View installed updates. The Installed Updates are displayed.
